Recovering Gold through the Froth Flotation Process

 · Froth flotation works by exploiting the hydrophobic properties of gold molecules. First ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry which is mixed with surfactants to increase the gold s hydrophobicity. This mixture is placed into a large tank filled with distilled water.

The Effect of Collectors and Their Interactions with

Collectors are used to impart hydrophobicity on particles thus increasing their chances of reporting to the froth phase. Also the extent to which naturally hydrophobic gangue particles such as talcaceous minerals report to the froth can be reduced by the use of depressants. Thus the use of collectors and depressants will directly influence the extent to which hydrophobic particles report to
